Balance the following equation. choose "blank" if no coefficient other than 1 is needed. k + h20 h2 + koh

The balanced chemical reaction;

Explanation:

The balanced chemical equation will be is given as :

By the stoichiometry of the reaction , 2 moles of potassium metal reacts with 2 moles of water to give 1 mole of hydrogen gas and 2 mole potassium hydroxide.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
